Abstract

The European Union Guidelines to Good Manufacturing Practice (EU GGMP) includes a recommendation for a 'clean-up' of airborne particles in the cleanroom after completion of operations, where the concentration should decay by up to 100, or 10 fold, in 15 to 20 minutes. When designing a ventilation system for non-unidirectional airflow EU GGMP Grade B and C cleanrooms, it is necessary to determine if the proposed air supply rate will be sufficient to provide the air change rate for the clean-up specified in the EU GGMP, and such a method is provided in this article. The air change rates for other decay times and reductions in particle concentrations in cleanrooms can also be calculated by this method.
